To begin your week, Panzer has a free ebook download site for you.
1) Booko Bookworm's Club: The free ebooks here are arranged by category to make it easy for you to find what you're looking for. Amazon is the first site listed (of course), but other free sites are here as well. You will need to join to be able to access the free ebooks, but it's simple.
You can find other free sites we've listed here before at Free Ebooks and Free Kindle Ebooks.
